Calculate Sample Size Needed to Compare 2 Proportions: 2-Sample, 2-Sided Equality. This calculator is useful for tests concerning whether the proportions in two groups are different. Suppose the two groups are 'A' and 'B', and we collect a sample from both groups -- i.e. we have two samples.

Our American flag calculator uses the American flag proportions presented in Title 4 of the United States Code, § 1 and § 2. These American flag measurements ratios are: (C) Union height (Hoist of the canton) = 0.5385 (A × 7/13, spanning seven stripes); (D) Union width (Fly of the canton) = 0.76 (2/5 of the flag width);Step 3 Specify the formula. 100 ( 1 − α) % confidence interval for population proportion is. p ^ − E ≤ p ≤ p ^ + E. where E = Z α / 2 p ^ ( 1 − p ^) n and Z α / 2 is the Z value providing an area of α / 2 in the upper tail of the standard normal probability distribution.

A confidence interval has the property that we are confident, at a certain level of confidence, that the corresponding population parameter, in this case the population proportion, is contained by it. For the case the population proportion (. p. p p ), the following expression for the confidence interval is used: C I ( P r o p o r t i o n ...

A calculator to resize whilst maintaining the same proportions. A classic proportion wheel(aka proportion scale) is used by graphic designers to resize an image to fit within a target width (or height). The general idea is to translate a given width/height so the image doesn't get distorted, thereby maintaining the same aspect ratio.
